Enum ProviderError 

pub enum ProviderError {
    Http {
        context: String,
        source: Error,
    },
    Serde {
        context: String,
        source: Error,
    },
    Io {
        context: String,
        source: Error,
    },
    Config(String),
    Logic(String),
}

Errors produced by AI provider implementations and the shared tool loop.

Variants

Http

HTTP transport failure — request build, network error, timeout. context describes the operation; source is the reqwest::Error.

Fields

context: String

Human-readable description of the failing operation (e.g. “anthropic: stream request”, “build HTTP client”).

source: Error

The underlying reqwest error.

Serde

JSON serialization or deserialization failed.

Fields

context: String

Human-readable description (e.g. “anthropic: parse response”).

source: Error

The underlying serde_json error.

Io

A filesystem operation failed.

Fields

context: String

Human-readable description (e.g. “create .claude dir”, “write MCP settings”).

source: Error

The underlying I/O error.

Config(String)

Missing or invalid configuration — env var unset, bad model id, etc.

Logic(String)

Domain-logic error with no foreign source — provider rejected the request, retries exhausted, response shape mismatch, etc.

Implementations

impl ProviderError

pub fn http(context: impl Into<String>, source: Error) -> Self

Wrap a reqwest::Error with operation context.

pub fn serde(context: impl Into<String>, source: Error) -> Self

Wrap a serde_json::Error with operation context.

pub fn io(context: impl Into<String>, source: Error) -> Self

Wrap a std::io::Error with operation context.

pub fn config(msg: impl Into<String>) -> Self

Construct a config error from a message.

pub fn logic(msg: impl Into<String>) -> Self

Construct a domain-logic error from a message.

Trait Implementations

impl Debug for ProviderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProviderError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProviderError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ProviderError> for KernexError

Bridge to the workspace-level aggregate error.

Boxes the typed ProviderError inside KernexError::Provider so callers downstream can recover the structured cause via boxed.downcast_ref::<ProviderError>(). Config is hoisted to the dedicated KernexError::Config variant since it’s a configuration failure, not a provider failure.

fn from(err: ProviderError) -> Self

Converts to this type from the input type.
